Syrian Tank Shellings Draw Protest
Video posted on a social media website showing more protests across Syria.
Wednesday was one of the bloodiest days of the seven-week uprising - apart from the main Friday protest days.
At least 19 people were killed across the country as President Bashar Al Assad sent troops and tanks into several cities to try and crush the protests.
Protests took place in Damascus, Homs and Aleppo.
Most of the violence occurred in the southern Deraa province.
Human rights campaigners say that 13 people were killed in a town near Deraa when tanks shelled four houses.
Protesters have hardened their demands recently with many now calling for the overthrow of the President.
The crowds also chanted slogans calling the local media liars.
Syrian authorities have declined to comment.
They have banned most international media from Syria, making it difficult to verify accounts of events.
